The LV3000/LV4000 Series Continuous Level Measurement probes are the most flexible, as well as cost effective, level solutions for a great variety of applications. The built-in (one-piece) electronic module provides a 4 to 20 mA output (2 wire) signal that is proportional to the process level. The LV3000/LV4000 Series features a potentiometer to account for varying sensitivity according to the medium or product, tank dimensions, rod length, position of installation as well as other application features.

Rods can be coated with PTFE as an option. The wide range of applications for RF analogue level measurement probes (such as liquids and pastes), requires attention in selecting the correct level probe and installing it in the proper location. The probe is the primary measuring element and must be capable of producing enough capacitance variance as it becomes submerged in the measured product. To cater to all applications, OMEGA’s capacitance probes are offered with different designs and features. The success of how the probes are applied depends on these important factors:

A) Materials that are conductive can cause a short circuit between a bare stainless steel probe and the tank wall. As the liquid level drops, the probe remains wetted, providing a conductive path between the probe and the tank wall. The faster the level changes, the more likely this false indication is to occur. For this situation, we recommend the use of PTFE or other types of insulator coatings on the rod surface.

B) Material build-up also affects the accuracy of RF capacitive measurements, and therefore additional adjustment to the probe’s sensitivity is recommended. Housings must also be compatible with the requirements for hazardous, wash-down, wet, and/or dusty environments. Explosion proof environments may require the housing to be certified. In addition, the active probe might need to be intrinsically safe or have an intrinsic safety barrier. The electronic circuitry of the probe performs several functions such as rectifying and filtering the incoming power, generating the radio frequency signal, measuring the changes in current flow, analogue signal generators and display meters. The circuitry is provided with potentiometer adjustments for setting sensitivity that is located in the housing of the probe. These adjustments give an added level of fine tuning which enable our customers to control the probes’ sensitivity with greater accuracy.

The LVCN4300 Series point level switch probe works as a remote probe and is compatible with the LVCN400 series relay. This combination allows the electrode to be used in temperatures up to 177°C (350°F). The LVCN4300 is a very compact 316SS switch.
